Good morning , ladies and gentlemen ,

Some of us are having problems with our parents , as they often look into our school bags or read our diaries . I fully understand why we are not comfortable about it , but there鈥檚 no need to feel too sad. Our parents are checking our bags or diaries to make sure we are not getting into any trouble . They have probably heard some horrible stories about other kids and thought we might do the same . Or perhaps they just want to connect with us but are doing it all wrong . My suggestion is : Tell them we want them to trust us as much as we鈥檇 like to trust them .If you don鈥檛 think you can talk to them , write them a letter and leave it lying around ---they are bound to read it .

Thank you!

1，因为角A=70°，角BGE=70°，所以AM‖EF（同位角相等，两直线平行）；
角CHG=110°，所以角搏雀DFG=70°，（平角定义），所以角DFG=角BGE，所以AB‖CD（同位角相等，两直线平行）。
2，角1=角2，所以A‖B（同位角相等，两直线平行）；角3=角4，所以B‖C，所以A‖C（平行线有传递性）。
3，因为DE平分角ADC，所以角ADE=角EDC，又因为角ADE=角AED,所以角AED=角EDC,所以AB‖CD（内错角相等，两直线平行嫌旅），所以角DEB+角FBE=180°，又因为角AED+角DEB=180°，所以角AED=角ABF,所以DE‖BF（同位角相等，两直芹银凳线平行）。

1，因为角A=70°，角BGE=70°，所以AM‖EF（同位角相等，两直线平行）；
角角CHG=110°，所以角DFG=70°，（两角相加是平角），所以角DFG=角BGE，所以AB‖CD（同位角相等，两直线平行）。
